After an engine failure I landed my Turb upside down in a field of barley that looked like a pasture from the air, but it wrapped round the langing gear and flipped me over. I was using a motor cycle crash helmet, but of course no radio back then. No injury, but incredibly hard to exit the aircraft. In doing so I kicked the fuel cock off! As a side note, had what seemed like half of the Surrey police force out, thinking I was a downed airliner. I had flown ove a police sports field and they had called in an emergency. But would you believe that the officer in charge loaned me two poicement to help remove the wings and truck the aircraft home. Nice folks! Had to make a new prop though!!
